Check Digit Verification of cas no

The CAS Registry Mumber 1353552-55-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,3,5,5 and 2 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1353552-55:
(9*1)+(8*3)+(7*5)+(6*3)+(5*5)+(4*5)+(3*2)+(2*5)+(1*5)=152
152 % 10 = 2
So 1353552-55-2 is a valid CAS Registry Number.

Solid phase synthesis of 1,5-disubstituted pyrazole-4-hydroxamic acids and pyrazole-4-carboxamides via direct amidation of β-ketoesters

Zhai, Weixu,Gerritz, Samuel W.,Sofia, Michael J.

, p. 267 - 270 (2012)

This manuscript describes a convenient method for the direct amidation of methyl and ethyl β-ketoesters to generate solid-supported β-ketohydroxamates or β-ketoamides and the application of this methodology to the synthesis of 1,5-disubstituted pyrazole-4-hydroxamic acids and pyrazole-4-carboxamides.
